[chbot] Has anyone used the HMC5883L digital 3-axis compass chip?

Hi, 

I've got a couple of these as part of a cheap-and-cheerful
9DOF+Atm Pressure board. 

I've found it very easy to work with, either
from a PI (all sensors):

or from an FPGA (just the compass):

I've got a couple
of boards spare if you want to borrow and maybe arrange a replacement if
you want to hold onto it. 

Mike. 

PS. I'm off to the Atlanta for a 3
day training course on Sunday, so I can bring em into the office
tomorrow (Durham St South), or you can pick them up in Springston
(outside Lincoln) on Saturday.
